"They were living together, they hadn't split," he told the Australia Daily Telegraph . "I'm worried about his mental state, to be honest. I don't know how he'll cope without George."

When he failed to revive George, fine art photographer Fadi called police and then 28-year-old Josh, sobbing down the phone to him.

"I've never heard a grown man cry so much. Fadi called me saying 'what am I going to do without him?'," Josh told the newspaper.

"They spent almost every day together for six years. He was so upset, he had been crying at the house beside George and I believe he found him dead."

Fadi has since been helping police and underwent a five-hour grilling with detectives to clarify what he saw in George's Goring-on-Thames mansion.

Josh went on: "Fadi has had the finger pointed at him but it's all bull***t.

"There was nothing but love in that relationship; he has been called a leech and all sorts, but he never took advantage or would do anything to hurt George."

After deleting his 'hacked' Twitter following a string of tweets hinting that George was having suicidal thoughts, Fadi appeared back on the social network this week to slam reports that he and George had split.

Following newspaper claims that George had been trying to get Fadi out of his life for the last 18 months, Fadi branded them "lies" and told the outlet in question: "Time you believed in love."

Toxicology tests will now be run, although the results won't be back for several weeks.
